Chelsea suffered a nightmare start to their Premier League title, having two men sent off as Burnley claimed a superb win at Stamford Bridge.
It would be easy but misleading to lay the blame for the Blues’ defeat on the decision to show a red card to new club captain Gary Cahill for a lunging tackle on Steven Defour midway through the first half.
But that would deprive Burnley their due for an energetic display that saw them score three times before the break, with Sam Vokes netting twice.
The Blues were better after the break and pulled a goal back when summer signing Alvaro Morata headed in shortly after coming off the bench.
However, the Spaniard was also at fault for denying the home side a second goal, adding an unnecessary touch to Andreas Christiansen’s goal-bound shot from an offside position.
Chelsea’s hopes looked to have gone when a late challenge from Cesc Fabregas on Jack Cork added a second yellow to the a first he received for dissent to leave the Blues with nine men.
But David Luiz fired home from inside the box after being set up by a Morata header to set up a frantic final few minutes, during which Burnley struck the post through Robbie Brady before holding on to take the three points.
